What is the primary use of STRSW in collision repair?

• A. Attaching replacement panels at factory spot weld locations
• B. Finishing cosmetic beads
• C. Cutting metal panels
• D. Sealing joints

Answer: (A)

STRSW refers to stitch welds used to reattach a replacement panel at the same factory spot weld locations. In collision repair, when you replace a panel, you want to recreate the original joining method so the panel aligns correctly and the vehicle’s structural strength is preserved. Using short, spaced welds along the joint (often at the factory locations) minimizes heat distortion and helps the new panel seat properly against the existing structure. This approach also allows precise alignment before final sealing or finishing. It isn’t about finishing cosmetic beads, cutting metal panels, or sealing joints, which are handled with different techniques and tools.
